Contractor Financing for Customers: The 2026 Lender Comparison and Close-Rate Math

Offering contractor financing inside the quote lifts close rates by 20-40% on jobs over $5,000, per benchmark data from Synchrony’s home improvement financing program and Service Finance Company dealer reporting. On HVAC system replacements above $8K specifically, the lift is 10-18 close-rate points on its own.

The mechanism is not magic. A homeowner staring at a $13,000 cash quote is comparing that number to savings they do not have. The same homeowner staring at a $160-per-month payment is comparing it to the $185 electric bill they already pay every month. Same job, same price, completely different decision frame.

This is the 2026 buyer’s view on contractor financing for customers: the 5 lenders that home service shops actually run, what each one costs in merchant fees, the 0% promo math that decides whether a deal is profitable, and the integration points that turn financing from a flyer on the truck into a closing tool on the iPad.

Why financing matters more in HVAC, roofing, and plumbing replacements

The trades where financing moves the needle have three-figure tickets and four-figure decisions: HVAC replacements ($8,500-$16,750), roofs ($9,000-$22,000), water heaters with electrical upgrades ($3,500-$6,500), full repipes ($6,000-$15,000), standby generators ($8,000-$15,000).

At those numbers, homeowners shop. Most get 2-4 bids per job over $5K. A $13K bid presented as a cash number on an estimate pad loses to a $14K bid presented as a $165 monthly payment, even when the $13K shop is the better installer.

Contractor financing is not a fallback for broke customers. The largest segment is dual-income households with 720+ FICO who could pay cash but prefer to keep savings liquid. Wisetack’s 2026 financing benchmark shows the average approved customer has a 730 FICO and $98K household income. These are buyers protecting their emergency fund, not subprime borrowers.

A shop that mentions financing only when the customer asks finances 5-10% of jobs. A shop that presents financing as a monthly payment on every quote tier finances 35-55% of jobs and closes 20-40% more deals at higher average tickets. The pricing lever and the financing lever compound. For the full pricing system, see our HVAC pricing guide.

The 5 contractor financing lenders home service shops actually use

There are dozens of lenders pitching contractor programs. Five own the home service market in 2026.

Wisetack

Easiest entry point for shops under $2M revenue. No enrollment fee, no monthly minimums, no chargebacks on approved loans. Soft credit pull approval in 60 seconds with a text link.

2026 merchant fees: 0-7.9% on prime borrowers (700+ FICO) on standard APR plans. Higher fees on subsidized promos. Consumer APRs range 0% to 35.9%.

Best for: Plumbing, electrical, HVAC service work $1K-$15K. Single-truck and small multi-truck shops.

Watch out for: Does not match GreenSky or Service Finance on deep-subsidized 0% promo terms for larger HVAC installs. For $15K+ tickets, Wisetack is a complement, not a replacement.

GreenSky (Goldman Sachs)

GreenSky was acquired by Goldman in 2022 and sold to a Sixth Street consortium in 2024. Still the largest home improvement financing platform in the US with over $30B in originations, dominant in HVAC, roofing, and windows.

2026 merchant fees: 0% on standard 9.99% APR plans, 4.99-12.99% on 0% promotional plans (6-24 month deferred interest), 6.99-9.99% on reduced-rate plans (3.99-7.99% APR over 60-120 months).

Best for: Multi-truck HVAC and roofing shops doing $5M+ revenue that need 0% APR firepower to close $15K+ replacements.

Watch out for: Goldman-era underwriting got noticeably stricter. Approval rates dropped 8-12 points across most contractor programs in 2024-2025, especially at the 660-700 FICO range.

Synchrony Home

Synchrony Home is the contractor arm of Synchrony Bank (Care Credit, major retailer cards). Strong in HVAC, kitchen and bath, outdoor living.

2026 merchant fees: 0% on standard 9.99% APR. 3.99-11.99% on 0% deferred interest promos (12-60 months). Special multi-tier promos for Carrier, Trane, and Bryant dealers.

Best for: HVAC shops on Carrier, Trane, or Bryant dealer programs with negotiated preferred Synchrony rate sheets. Also strong in kitchen/bath remodelers.

Watch out for: Deferred interest is the trap. If the customer does not pay the full balance by promo-end, Synchrony retroactively bills all accrued interest from day one (typically 28.99% APR). Set expectations explicitly or you will get the angry call 13 months later.

Service Finance Company

Service Finance Company (SFC) is the lender most deeply embedded in HVAC and roofing manufacturer dealer programs. Lennox Premier Dealers, Carrier President’s Award dealers, and GAF Master Elite roofers usually have SFC already in the tech app.

2026 merchant fees: 7-11% on 0% APR 12-24 month promos. 4-7% on extended 0% APR 60-month promos. 1-3% on reduced-rate plans. 0% on standard 9.99% APR.

Best for: HVAC replacements, roofs, windows, any dealer-program shop where the manufacturer has subsidized promo rates.

Watch out for: Contractor-facing customer service is the most-complained-about in the category. The lending mechanics work; the back office is slow. Expect 24-72 hour funding instead of next-day.

Sunlight Financial (Cross River Bank)

Sunlight Financial was the largest residential solar lender before its 2024 bankruptcy and Cross River acquisition. Now reorganized, it serves solar, battery storage, and high-ticket heat pump installs.

2026 merchant fees: 8-22% on long-term solar loans (20-25 year terms), amortized into the consumer rate. Lower fees on heat pump and battery-only loans (5-12%).

Best for: Solar installers, battery storage shops, HVAC contractors doing $20K+ ducted heat pump retrofits with IRA tax credits stacked.

Watch out for: Post-bankruptcy Sunlight is a different lender than the 2022 version. Approval criteria tightened. Confirm your dealer agreement is current before quoting Sunlight terms.

The 0% promo math: who actually pays for the interest

Every 0% APR contractor financing promo is subsidized by someone. There is no free money from the lender.

For a $13,000 HVAC system on a 0% APR 18-month promo with a 9% dealer fee:

• Customer pays: $13,000 in 18 monthly installments of $722. No interest.
• Lender pays out to contractor: $13,000 - (9% x $13,000) = $11,830
• Contractor net before job costs: $11,830
• Lender keeps: $1,170 as their fee for carrying the loan and forgoing interest.

The contractor is effectively financing the 0% promo through the dealer fee. The customer sees “no interest” and feels good. The lender gets paid. The contractor is the one who gave up margin.

This is fine when the math works. If the job’s gross margin was 35% on a $13,000 cash price ($4,550), giving up $1,170 in dealer fees still leaves $3,380 in gross profit. The 0% promo closes deals that would not have closed at cash, so the trade is positive.

The math breaks when shops offer 0% on jobs with thin margins. A $4,000 plumbing repipe at 22% gross margin nets $880. Put it on a 0% APR 12-month promo at a 7% dealer fee ($280) and the net drops to $600. At that point the financing offer is destroying the job.

Most successful 2026 shops use a two-track financing menu:

• 0% APR promos available on tickets over $8,000 (HVAC replacements, full roofs, repipes) where the close-rate lift is worth the 7-12% fee.
• Standard 9.99% APR plans with 0-2% fees on smaller tickets ($1K-$8K) where the contractor keeps the full margin and the customer still gets a monthly payment option.

Bake the dealer fee into the price book so the cash and financed prices match. A homeowner who sees “$13,000 cash / $13,800 if financed” will pick cash or walk to the next bid. A homeowner who sees “$13,000, or $722/month for 18 months” picks one of the two and signs.

Integration with field service and quoting tools

The financing lift only happens when the monthly payment is on the quote at the moment of decision. A flyer on the truck and a “we offer financing” line in the email follow-up gets ignored.

The integrations that matter in 2026:

• ServiceTitan + GreenSky/Synchrony native integration pre-calculates monthly payments inside the proposal builder and runs soft-pull approval from the tech’s iPad. The customer signs the financing application inside the same app session as the install agreement.
• Housecall Pro + Wisetack integration sends the financing offer as a text link from the in-home estimate. Customer applies in 60 seconds. Approved customers sign the install agreement on the spot.
• JobNimbus + GreenSky for roofing shops puts the financing math directly into the proposal PDF so the homeowner sees the monthly payment on the same screen as the shingle selection.
• Aspire + Synchrony Home integration for landscape and outdoor living shops bundles 0% promos for hardscape and pool installs into the contract workflow.

For shops still on disconnected tools (separate price book, separate financing portal), the friction kills 60-70% of the close-rate lift. The tech has to remember to mention financing, open a different app, run the application, wait for approval, switch back to the quote, recalculate the payment, and re-present. By the third manual step, most techs skip it. For the upstream picture on quoting, see our HVAC quoting software comparison.

How to present financing on the quote

The presentation matters more than the lender. Three rules:

1. Lead with the monthly payment, not the APR. Homeowners do not calculate amortization in their heads. They know what their electric bill is. Frame the financing in language they already use: “$160 a month for 120 months, which is about what you pay for streaming services and one of those weekly meal kits.”

2. Show the payment on every tier of the quote. If you run good-better-best (and you should), the basic, mid, and premium tiers each get a cash price and a monthly payment line. The middle tier becomes the obvious pick when the financing math makes the premium look reachable instead of impossible.

3. Pre-fill the application on the iPad before the homeowner asks. The tech opens the financing app, enters the price and term, and shows the screen. The customer either says “tell me more” or “I’ll pay cash” within 30 seconds. Either answer is faster than waiting for them to bring it up.

A roofing owner on r/Roofing posted his close-rate math after switching from a paper financing flyer to in-quote presentation on JobNimbus with GreenSky. Old close rate at $14,200 average ticket: 31%. New close rate at $14,800 average ticket: 47%. Same crew, same neighborhoods, same shingles. The only change was the financing math being visible at decision time instead of after.

A multi-truck HVAC owner on the Owned and Operated podcast described the financing presentation shift as the second-highest-ROI change he made after price book discipline. Ticket held at $14,400 (already optimized). Close rate moved from 38% to 51%. Revenue per estimate went from $5,472 to $7,344, a 34% lift with no marketing spend changes.

The common contractor financing mistakes

Patterns from contractors who tried financing and gave up before it worked:

• Mentioning financing only after the customer says the price is too high. By that point the customer is mentally at the next bid. Silence reads as “this shop does not offer it” and 70-80% of homeowners will not ask.
• Offering 0% APR on every job. The 7-12% dealer fee destroys margin on small tickets. Reserve 0% promos for jobs where they actually move close rate. Use standard 9.99% APR with 0-2% fees elsewhere.
• Hiding the dealer fee with a financing surcharge. Charging a “3% financing fee” is illegal in most states. Bake the fee into the price book so cash and financed prices are identical.
• Picking one lender and stopping there. Different lenders approve different credit tiers. A GreenSky-only shop misses the 660-700 FICO customers Wisetack would have approved. The 2026 standard is a primary lender plus a backup for fallback approvals.
• Letting techs explain deferred interest verbally. “If you pay it off in 18 months it’s 0%” is operationally a disaster. Miss the deadline by a day and Synchrony retroactively bills 18 months of 28.99% interest. Use the written disclosure and have the customer e-sign it during the application.

The lender funds the job in 1-3 days regardless of when the customer pays. For the broader payment process picture, see our guide on invoicing as a contractor.

The honest take

Contractor financing is the highest-leverage single change most home service shops can make to close rate and average ticket in 2026. The math is uncomfortable (giving up 7-12% on promo deals) but the close-rate lift is consistent across HVAC, roofing, plumbing, and remodeling data.

Shops that get it right treat financing as a default offer on every quote over $3K, run a two-track menu (0% promos for the jobs that justify the fee, standard APR for the rest), pick lenders based on credit-tier coverage rather than brand loyalty, and present the monthly payment inside the quote tool.

Shops that get it wrong run a single lender as a courtesy, mention financing only when the customer pushes back on price, and wonder why their close rate is stuck at 22% while a competitor on the same street is closing 41% on the same equipment.

The lever is real. The execution is the gap. For shops building a full pipeline system around higher-ticket buyers, see our marketing automation for contractors guide and the HVAC marketing agency comparison.
